Late-time particle emission from laser-produced graphite plasma
We report a late-time “fireworks-like” particle emission from laser-produced graphite plasma during its evolution. Plasmas were produced using graphite targets excited with 1064 nm Nd: yttrium aluminum garnet (YAG) laser in vacuum. The time evolution of graphite plasma was investigated using fast gated imaging and visible emission spectroscopy. The emission dynamics of plasma is rapidly changin...
متن کاملCharacterization of Expanding Laser Plasma Produced by Laser Ablation
This work is devoted to characterizing the plasma produced by nanosecond laser ablation. The expanding plasma was generated by the interaction of a home made XeCl excimer laser with a Cu target. The time-of-flight method was utilized as diagnostic tool of the plasma charged particles. By this method, in fact, we were able to measure the ion and electron currents, the charge-states and the energ...
متن کاملFine structure in the time of flight distribution of C2 in laser produced plasma from graphite
Time resolved optical emission spectroscopy is employed to study the expansion dynamics of C2 species in a graphite plasma produced during the Nd : YAG ablation. At low laser fluences a single peak distribution with low kinetic energy is observed. At higher fluences a twin peak distribution is found. It has been noted that these double peak time of flight distribution splits into a triple peak ...
متن کاملCollective behavior of laser-produced plasma from a multicomponent YBa2Cu3O7 target in air
The dynamics of diffusion of electrons and ions from the laser-produced plasma from a multielement superconducting material, namely YBa2Cu3O7, using a Q-switched Nd:YAG laser is investigated by time-resolved emissionspectroscopic techniques at various laser irradiances. It is observed that beyond a laser irradiance of 2.6×1011 W cm−2, the ejected plume collectively drifts away from the target w...
متن کاملParameters of a laser produced plasma from XUV line profiles
2014 The region of interaction between a focused 1 GW ruby laser beam and a plane beryllium target has been observed end-on with a high resolution stigmatic grazing incidence spectrograph. The profile of the Ly03B1 line of BeIV is made up of two components : a broad asymmetric one, spatially corresponding to the radiation emitted by the high density ablation region and a narrow one superimposed...
